Erickson Dimas-Martinez’s defense attorneys continued to present testimony Friday in an effort to convince jurors not to impose a death sentence for their client.

Erickson Dimas-Martinez, 24, was found guilty Thursday, March 25th, 2010, of aggravated robbery and capital murder in the death of Derrick Jefferson, 17. Jefferson was shot and killed Dec. 30, 2006. His body was found in the driveway of a Springdale home. He died of a single gunshot to the head.
